The advantages of investigators team. The PI and most of the co-PIs come from the same research lab-Healthy Aging Research Center, Cognitive and Behavioral Indices Lab, Chang Gung University. This lab targets on populations such as normal older adults and those with dementia and disability. Investigator have developed own assessment tools and platform used to share the data such as the Prospective and Retrospective Memory Questionnaire (PRMQ). In the future, Investigator may share imaging technology. Therefore, investigators team has the advantages of integration of expertise. Interactions between experts will facilitate the progress of this project. Specifically, Dr. Hsu (a neurologist) will provide the clinical utility that ensures formal diagnosis and assessment for PWCIs. The external consultant (a psychologist), Professor Hua, will assist in administering psychometric tests, interpretation of data, and consultation on the content of intervention. Investigator have international collaboration partners such as Professor Jersey Liang from the University of Michigan, USA for longitudinal and experimental data analyses consultation and Dr. Heather Wilkinson from Edinburgh University, UK to focus on the dementia friendly community issues. Investigator hold monthly research meeting in the lab. Finally, the PI has research collaboration with Professor Heh, Chung Yuan Christian University, on the work of interactive mathematic training APP for MCI patients. Based on this foundation, Investigator will continue to develop the EMS in this project.
